Disk pool costs and limitations

You may encounter specific limitations when you use disk pools (auxiliary storage pools):

• The system cannot directly recover lost data from a disk unit media failure. This situation requires you to perform recovery operations.
• Using disk pools can require additional disk devices.
• Using disk pools will require you to manage the amount of data in a disk pool and avoid an overflown disk pool.
• You will need to perform special recovery steps if a basic disk pool overflows.
• Using disk pools requires you to manage related objects. Some related objects, such as journals and journaled objects, must be in the same user disk pool.
